Cracked rotors from track use

I posted video before of my improved lap times, but this time it was at the cost of my rotors. I switched pads and fluid but kept the stock rotors. Turns out that when you remove the weak pads, crappy fluid, and standard lines the rotors then become the weak point. I think pixelblue made some cooling ducts which had I done that would have eliminated some of the heat, but I failed to do that and now am stuck with a very costly fix.

For those just replacing pads and tracking your car beware the cross drilled rotors are very prone to cracking without some form of heat reduction. Live and learn I suppose.

I am going to use it as an excuse to get a bbk, but damn that was an expensive lesson. Full Stoptech kit isn't in stock so I would have to wait 4-6weeks, so I am stuck with the Brembo's.
